An international team of scientists led by Gina Moseley from the Department of Geology at the University of Innsbruck presents the very first analysis of sediments from a cave in northeast Greenland, that cover a time period between about 588,000 to 549,000 years ago. This interval was warmer and wetter than today, the cave deposits provide an outlook in a possible future warmer world due to climate change. The study has now been published in the journal Science Advances.

The first imaging of substantial freshwater plumes west of Hawai'i Island may help water planners to optimize sustainable yields and aquifer storage calculations. University of Hawai'i at Mānoa researchers demonstrated a new method to detect freshwater plumes between the seafloor and ocean surface in a study recently published in Geophysical Research Letters.

It was Harlock's first day at coronavirus training school and she already showed promise.

An enormous telescope complex in Tibet has captured the first evidence of ultrahigh-energy gamma rays spread across the Milky Way. The findings offer proof that undetected starry accelerators churn out cosmic rays, which have floated around our galaxy for millions of years. The research is to be published in the journal Physical Review Letters on Monday, April 5.

Researchers with the Wildlife Conservation Society's (WCS) Congo Program and the Nouabalé-Ndoki Foundation found that female putty-nosed monkeys (Cercopithecus nictitans) use males as "hired guns" to defend from predators such as leopards.

Researchers studying mercury gas in the atmosphere with the aim of reducing the pollutant worldwide have determined a vast amount of the toxic element is absorbed by plants, leading it to deposit into soils.

An analysis of film tropes—common storytelling elements seen in different movies—explores combinations of tropes that tend to co-occur in films, identifying patterns that could help inform development of new movies. Pablo García-Sánchez and Juan Merelo of the University of Granada, and Antonio Velez-Estevez and Manuel Cobo from the University of Cádiz, Spain present these findings in the open-access journal PLOS ONE on March 31, 2021.

Even with spectators absent from matches during the Covid-19 pandemic, European professional football teams playing on their home ground enjoy a significant edge over visiting teams, a new study showed Wednesday.

After the optical frequency comb made its debut as a ruler for light, spinoffs followed, including the astrocomb to measure starlight and a radar-like comb system to detect natural gas leaks. And now, researchers have unveiled the "agricomb" to measure, ahem, cow burps.

University of California, Irvine, biologists have discovered that plants influence how their bacterial and fungal neighbors react to climate change. This finding contributes crucial new information to a hot topic in environmental science: in what manner will climate change alter the diversity of both plants and microbiomes on the landscape? The paper appears in Elementa: Sciences of the Anthropocene.

Archaeologist Stephen Sherlock, an independent scholar, has found evidence of Neolithic people extracting salt from seawater 5,800 years ago at Street House, Loftus, making it the oldest salt production facility ever discovered in Britain. He has published a paper outlining his findings on the Cambridge University Press site, Cambridge Core.

A team of researchers from the University of Oklahoma, and one from the University of Notre Dame, has found that on July 27, 2019, approximately 46 million pallid-winged grasshoppers hovered over Las Vegas, Nevada—one of the brightest-lit cities in the United States. In their paper published in the journal Biology Letters, the group describes using radar data to study the grasshoppers.

A pair of researchers with Indiana University and Illinois University, respectively, has developed a theory that suggests crystalizing uranium "snowflakes" deep inside white dwarfs could instigate an explosion large enough to destroy the star. In their paper published in the journal Physical Review Letters, C. J. Horowitz and M. E. Caplan describe their theory and what it could mean to astrophysical theories about white dwarfs and supernovas.

Using the Neutron Star Interior Composition Explorer (NICER) instrument aboard the International Space Station (ISS) and NASA's Swift spacecraft, astronomers from India have investigated an X-ray pulsar known as 2S 1417–624. Results of the study, published March 24 on arXiv.org, provide important information about the evolution of different timing and spectral properties of this source during its recent outburst.

More research is needed on the environmental impact of sunscreen on the world's coral reefs, scientists at the University of York say.

Anthropogenic climate change is one of the foremost scientific and societal challenges. In part, our response to this global challenge requires an enhanced understanding of how the Earth's surface responds to episodes of climatic heating and cooling. As historical records extend back only a few hundred years, we must look back into the ancient rock record to see how the surface of the Earth has responded to shifts between icehouse (presence of ice at the Earth's poles) and greenhouse (no substantial ice at Earth's poles) climates in the past.

Oregon State University researchers broadcast marbled murrelet calls in mature forests and found that the threatened seabirds' choice of breeding locations is strongly influenced by whether they hear other murrelets in the area.

In the run up to hibernation, grizzly bears go on a colossal binge, consuming as many calories as possible to get them through the long winter. Yet, little was known about how much energy the massive mammals use as they shamble around their rugged territories. "Moving across the landscape in search of food can be a huge energetic expense for some animals," Carnahan says. Fortunately, the Washington State University Bear Research, Education and Conservation Center (WSU BREC), where Carnahan is based... Читать дальше...

Research published today in the peer-reviewed Journal of Vertebrate Paleontology describes a newly discovered species of dinosaur—named the 'one who causes fear', or Llukalkan aliocranianus.

Rock art of human figures created over thousands of years in Australia's Arnhem Land has been put through a transformative machine learning study to analyse style changes over the years.
